Despite the Swiss-born socialite being awarded $2.5 billion (Â£1.7 billion) from her former elite art dealer and horse-racing husband, Alec, in the late 1990s in one of the biggest divorce settlements in history, she claimed in the past week that she's broke.
DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).The order of these bases is what determines DNA's instructions, or genetic code.ach nucleotide contains a phosphate group, a sugar group and a nitrogen base.

1 A molecule of a DNA polymerase binds to one strand of the DNA and begins moving along it in the 3' to 5' direction, using it as a template for assembling a leading strand of nucleotides and reforming a double helix.2  In eukaryotes, this molecule is called DNA polymerase epsilon (Îµ). DNA replication begins with the unzipping of the parent molecule as the hydrogen bonds between the base pairs are broken.
